COMBINED WASHING AND RINSING MACHINE Filed Dec. 4, 1957 INVENTORATTORNEYS,

Patented June 6, 1939 y UNITED STATES PATENT OFFICE COMBINED WASHING ANDamsmc momma I Louis De Marco, Cleveland, Ohio Application December 4,1937. Serial No. 178,116 6 Claims. (01. oa -s3) parts shown in thedrawing hereof, wherein Fig.

1 represents a central vertical sectional view through the upper portionof a washing machine embodying my invention and Fig. 2. a' plan view ofthe machine shown in Fig. 1.

Describing first the construction shown in Figs. 1 and 2, I denotes thetub, the same having a bottom 2 and a supporting base 3, which may be ofany standard construction. 4 denotes a hollow standard which is securedat its lower end to the bottom 2 as by means of a nut5, there being awasher 8 interposed between the said nut and the portion of the bottomsurrounding'an opening 12a therethrough. A

1 denotes the housing for the mechanism which'drives the shaft 8, thelatter having a squared upper end 9 received within a Cortespondinglyshaped socket I! in the top of the rotor body III, the said'body beingprovided with the usual blades ll.- l2 denotes a bearing which isinterposed between the upper portion of the shaft and the standard 4,and I3 a similar bearing which is interposed between the standard andthe lower portion of the rotor body. V

The construction and arrangement of the foregoing parts are those usedin a well-known type of standard washing machine and need no furtherdescription. v r

In order to convert the machine thus shown and described into anefiective rinsing'machine, 40 I have providedthe following construction:l4 denotes a cover having a central opening it by means of which it maybe set down within the tub, below the top of the rotor body. This coveris provided with openings IQ for the passage of the rinsing water andwith a gasket l'l set within an annular channel I! formed within theouter periphery of the cover, thereby to insure a substantiallyleak-proof engagement between the cover and the inner wall of the tuband to serve as a bumper to prevent marring the said wall.

The cover issupported in proper relation below the top of the standard 4by means of locking means carried by ribs l9 preterably integral withthe cover and extending upwardly and outward- 1y from the centralopening l5. As shown, these ribs comprise each a widened top connectedintermediate its inner and outer ends to the body of the cover by a-web24. The webs of the ribs may be considerably shorter than the tops thereof, thereby to provide large openings 2| through which the water flowingthrough the openings I may be delivered freely to the outlet. Pivoted tothe upper ends of the ribs I! are the swinging supports 22 for thelatches .22, the latches being pivoted to the lower ends of the members22 and adapted to engage beneath an outturned flange 24 at the top ofthe tub. v

25 denotes a waste spout extending along the outer side of the tub andhaving its upper widened end 25* located immediately above the cover I4.I

26 denotes a valve body which is secured to the bottom of the tub andthe portion of the side adjacent thereto, as by rivets 2". 21 denotes arotary plugmounted within the valve body and The operation of thecombined washing andrinsing machine thus far described will be readilyunderstood. The water for washing the.

clothes or other articles may be placed in the tub in the usual manner,or supplied through the pipe 29 which may, it desired, be connected withboth the hot and cold water pipes of the house. When the tub is filledfor washing purposes, the valve 21 will be in its cut-oi! position.After the tub has been filled, the soap will be added to the watertherein, and the rotor II- will be operated in the usual manner toagitate the articles in the tubl At the end of the washing operation,the valve 21 will be turned so as to drain the water from the tub, afterwhich it will be turned to the position shown in full lines in Fig. 1,and water from the pipe 29 will be supplied to the tub while the rotoris operating. This will enable water to pass in contact with and throughthe articles that have been washed while the latter are being agitatedby the rotor; and the soap and any sedi-' ment that may remain in thesearticles will be the openings in the cover l4 and being deliveredthrough the waste pipe 25. The openings it are preferably upwardlytapered or frusto conical, as shown, whereby to prevent the collectionof soap about the edges of the openings thereby to ia-' cilitate thedischarge of the soapy water therethrough.

The cover is provided with radially extending ribs I l M projectingdownwardly from th lower surface thereof. These ribs serve the doublefunction of preventing the articles from being forced into engagementwith the bottom of the cover and clogging the opening it as well ascooperating with the rotor in effecting speedy removal of soap andsediment from! the said article. o

It will benoted that the cover and the 'overflow outlet 25 are locatedbelow the top of the standard it. This enables the rinsing operation tobe performed without the liability of the water rising to andoverflowing the top of the standard and being delivered therethroughinto the'mechanism which operates the rotor.

The embodiment of my invention just discussed is applicable to existingwashing machines, without any material alteration in the tubs thereof.

It will now be clear that I have provided a combined washing and rinsingmachine which will accomplish the objects of the invention ashereinbefore stated.

Having thus described my invention, what I claim is? 1. A combinedwashing and rinsing machine comprising a tub, a central standardprojecting upwardly from the central portion of the bottom of said tub,a rotor having a body surrounding the said standard and extendingthereabove, a shaft mounted within the standard and extending throughand beyond the upper end thereof and connected with the rotor body,means for rotating the said shaft, connections 'for supplying waterunder pressure to the lower portion of the said tub, there being anoverflow for the water so supplied located below the top of the saidstandard, and a perforated cover supported by said tub and disposedbelow the overflow and having a central opening for the reception of theupper portion of the rotor body. I

2. In the combined washing and rinsing machine recited in claim 1, thecover having a gasket in the outer peripheryl thereof engaging the innerwall of the tub.

3. In the combination recited in claim 1, the

cover being provided with ribs extending upwardly and outwardly irom thecentral opening thereof, the upper end of the tub being provided with anoutwardly projecting flange, and locking devices carried by the upperand outer ends of the said ribs and adapted to be removably engagedbeneath the said flange.

4. A combined washing and rinsing machine comprising a tub having anoverflow, a rotor provided with agltatingmeans and located within thesaid tub, a cover located below the said overflow and above theagitating means and having openings therethrough, means for operatingthe said rotor, and connections for supplying water under pressure tothe lower portion of the said tub.

5. In the combined washing and rinsing machine recited in claim 4, thecover being provided with ribs projecting downwardly from the bottomthereof.

6. In the combined washing and rinsing machine recited in claim 1, thecover being provided with ribs proiectingdownwardly from the lowersurface thereof.
